Guidelines
Floors should be made of wood or
concrete or be covered with ceramic
tiles. If the floor is covered with
synthetic material, the relative
humidity must be at least 30%.
The quality of the supply voltage
should be that of a typical business or
hospital environment.
The quality of the supply voltage
should be that of a typical business or
hospital environment.
The quality of the supply voltage
should be that of a typical business or
hospital environment.
If the user of the 7752 scale requires
continued FUNCTION even in the
event of power supply interruptions, it
is recommended that the 7752 scale
be powered from an uninterruptible
power supply.
Magnetic fields at the mains
frequency should correspond to the
typical values found in the business
and hospital environment.
